The Origin of Asteroids, Meteroids, and Trans-Neptunian Objects

[Kevin Lea]

This chapter lays the foundation for understanding why asteroid origins remain one of the most fascinating topics in planetary science. Kevin examines trans-Neptunian objects, NASA’s DART mission, and evidence that many asteroids are low-density “rubble piles.” And explains why scientists are finding amino acids, nucleotide precursors, carbon compounds, and evidence of saltwater associated with asteroids and meteorites. Kevin and Bill also answer viewer questions about the composition and morophology of asteroids.

Check out the 55-gallon experiment with a layer of freshwater and saltwater plus fish from different habitats.

The fish would stay in the most comfortable regions of the volume of water similar to their preflood habitat.

Adaption has never produced macroevolution.
